A doctor is to visit a patient. From past experience, it is known that the probabilities that he will come by train, bus, scooter or by car are `(3)/(10), (1)/(5), (1)/(10), (2)/(5)` respectively. The probabilities that he will be late are `(1)/(4), (1)/(3), (1)/(12)`, if he comes by train, bus and scooter respectively, but if he comes by car he will not be late. When he arrives, he is late.
